Wow, went from an 11lb to 6lb trigger pull. Impressive. I also did stone mine since my lapping compound was frozen. I was about to send the AR on it's way because of the trigger, I won't spend $800+ on a firearm then have to spend another $150+ on almost required mods.

This is a must do before you drop $150 on a trigger that cost $15 to make. You won't regret the time spent.
